What does a solid yellow line between opposing lanes indicate?

• A. You may pass freely.
• B. You may pass only on the shoulder.
• C. No passing; you should not cross the line to pass.
• D. You should slow down and turn to the left to pass.

Answer: (C)

A solid yellow line between opposing lanes signals no passing. This line is placed where visibility or road conditions (like curves or hills) make passing dangerous, so crossing the line to pass could bring you head-on with oncoming traffic. You should stay in your lane and not cross the line to pass. You only pass when your side has a dashed yellow line and you can do so safely; otherwise, wait.
